After the Cray 1, he went on to the Cray 2, that was incompatible and not as cost-effective because he tried to simplify the Cray 1 architecture. If Cray 1 was the most expensive love seat; the Cray 2 was the most expensive fishbowl. It was so called because a liquid coolant was pumped among the modules. I saw the largest one with 8 processors at Livermore.

He took the Cray 2 design and the Cray 3 using gallium arsenide to form Cray Computer.

In 1987 SRC was formed to build computers using Intel CMOS Microprocessors.
